Application filed November17, 1908. Serial No. 463,065.

To all whom it may concern:

Be it known that I, FRANK BARTZ, a citizen of the United States,residing at Hornell, in the county of Steuben and State of N ew York,have invented a Meat Cutter, of which the following is a full andcomplete specification. i

My invention is an improvement in meatcutters, and relates moreespecially to that class which are driven by mechanical power, as anelectric motor, and are supported by the gear-casing attached to themotor. In this class of meat cutting machines it is desirable that themeat cutting device be detachable from the motor-so that it may be kept.in a refrigerator or conveniently cleaned. This care is requiredinasmuch as particles of meat remain in the cutting device after eachoperation, and'unless such.

particles are kept fresh by placing the meatcutter in a refrigerator,or-are entirely removed by cleaning the parts, they are likely to becomes oiled and affect a'batch of meat which may e subse uently operatedupon. In those instances W ere the machine is in frequent use it iscustomary to keep the meat cutter in'a refrigerator when it isnot inactual 0 eration rather than take the time. and troubl d of cleaning'itfafter each eriod of use, and as the whole machine shou d not beplaced-in the refrigerator, owing to the deleterious effect of theatmosphere on themotor, means must be provi ed to permit the meatcutting device of the machine to be detached. Unless such means providefor quickly and conveniently detaching the meat cutting device thetendency will be to move the entire machine notwithstanding the dangerto the motor.

he primary object of my invention, therefore, is to provide amotor-driven meat cutting machine in which the meat cutting device canbe readily attachedto and detached from the power mechanism, and whenattached will be fir y and securely held in place. My invention-consistsin providing the gear-casing of a meat cutting machine with w anengaging surface which: will cooperate with a corresponding surface onthe innerend ofthe meat. cutting device to-form an intimate connectionof the parts, 1n combination- Specification of Letters Patent.

with means for clam all as hereinafter fuly descrlbed and morespecifically set forth in the appended claims.

In the accompanying drawings, which form a part of this s ecification,and in which like numerals of re erence indicate like parts in alltheviews: Figure 1 is a side elevation of a meat cutting machineembodying my invention. Fig. 2 is a rear end elevation of the meatcutting device, showing one of the engaging faces. Fig. 3-is a frontelevation of the upper part of the the other engaging face. Fig.' 4 1s asectional view through the gear-casing and meat cutting device. v

Like numerals of reference indicate like parts in several figures of thedrawings.

Referring to the drawings, 5 designates a ing said parts togethergear-casing, showing motor, the inclosing case of which is adapted atone end for the attachment thereto of a casing fi, in w 'ch is mountedthe reducinggear and from which is supported the meat cutting device 7.In the present instance the reducing gear comprises a "gear f wheel 8,drivendirectly from the motor and having at v one side a pinion 9 inmesh vith a gear-wheel,

the forcing-screw through-and beyond the rear wall 17 of the casing orcylinder of the I meat j cutting device. The gudgeon 16 is provided atits, inner end with a round portion for hearing within said rear wall17.

For the purpose of cutting device 7 from the gear-casing 6 in suchmanner that it may be quickly and conveniently attached thereto anddetached therefrom I'provide thefront plate 13 of'the gear-casing withan enlargement or boss 18, which surrounds the bearing for thehub 12,

and in ,which are threaded a pair of winged supporting the m eat'thumb-screws 19, disposed at op of. said enlargement or boss.

osite sides I e enlargethereof, correspondin 18, are provided wit 0en-ended slots 21 gudgeon of the forcing-screw 0 thereof, rojects thehub 12' of the gearwheel 10, and as lateral extensions 18 near the outerends of which thethumb-screws are located. In order to coeperate withsaid boss the rear wall 17 of the meat cutting device is similarlyshaped, and the extensions 17 a with the extensio adapted to'receive thet umb-screws, and centrally the end wall 17 is provided with an Iannular boss 22, which enters the socket 20 and surrounds the hub 12. Byreference to Fig. 2 itwill beseen that one of the slots21 opens out atthe upper ed e of one extens1on o the end wall, andthat e other slotopens out at the lower edge of the other extension, for a purposehereinafter explained.

In connecting the parts the s uare ended the meat.- cutting device isfitted in the hub 12 of the gearing, the annular boss 22 entering thesocket 21 in the casing around said hub, and in this 0 eration theextensions 17 of'the rear we of the meat cutting device are so dis osedthat that slot opening out upwardly is elow one of the thumb-screws, andthe other slot, which opens out downwardl is above theother thumb-screw;so that w en the meat cutting device is turned saidslots will receivesaid thumb-screws, which latterma then be ti htened to clam the,partsto- It wil be understoo that in connecting the parts the thumb-screwsare not removed, but are'simply loosened suflicientlyv to permit theextensions 17 a to enter behind 'the heads of said screws. In det chingthe meat cutting device it is only he essary 'to loosen the thumb-screwsand turn said device sufficiently to disengage it fromthe thumbscrews,when it may then be removed by vwithdrawing. the udgeon from thehub ofthe gearwheel. will be readily seen, therefore, the operation ofconnecting the meat cutting device to the gear casing ofthe motor, aswell as the o eration of detaching it, may ineach instance e readily andquickly performed; thus making it convenient to remove the meat cuttingdevice for placing it in a refrigerator, or for other purposes. 4 Theopen ends of the slots 21 are-disposed 1n the direction of the rotationof the forcingscrew so that in the operation of the machine the motionof said forcing-screw will tend to retain the extensions 17 a inengagement with the screws, so that the clamping action of said screwsis not rehed-u on altogether.

Having thus descri ed myinvention, what Iclaim a mf desire to securebyLet- ,ters-Patent, i
